I am not sure that I know what harmonics-based SPICE is. Is it about AC analysis?

PLECS uses ideal switches, but now with SPICE integrated you can import any netlist to create a new block, including semiconductors.

It was brought to our attention that it would be interesting to have a good interface for ROM models. It seems like POD-based dimensional reduction is widely used in the industry. On the other hand, PLECS does have clever way to simulate th

We could call the state-space approach of PLECS quasi-symbolic, because it reduces circuits with linear components to state-space equations. As a result, it needs to solve for much fewer variables. The price to pay is that the obtained syst

Haha, ok fair enough. In the world of system-level integration of power electronics, SPICE is often considered the bottom. There is already a long way from an ideal on/off switch to a SPICE model of a MOSFET with a gate driver featurin

There was a lot of learning and reinventing to do. It started with a team of 1, and we eventually grew to a team 5. We all started working on it more or less fresh out of university. We were trained as mathematicians, physicists and computa

Roughly speaking yes, but Cadence has a large offering of products, so I need to be a little more specific. Ultimately, when you design analog devices with Cadence's tools, their transient behavior is simulated by Spectre (or FastSPICE

SPICE uses modified nodal analysis (MNA), which leads to differential algebraic equations (DAEs). This is very well-suited to detailed semi-conductor models (a bunch of convergence helpers are used behind the scenes to make the simulation o

I had to look into companion (discrete-time) models for simulating saturable inductors in real-time on FPGA at work. The same week, a friend asked out of curiosity where the inductor equation came from. It had been quite a while for me, so
